Hi ale and welcome to the forum,
There are some of us on the Total Colectomy 24 site that have had a colectomy and many wonderful people on all of the sites that would be willing to share information with you. I personally had a subtotal last July and my surgeon left 2 inches of my rectum. I have had an extremely successful surgery. I did have many bms in the beginning, like 20+ daily but once my small intestines took over I was down to 8-10 by 6 weeks and able to return to work full-time. By nine months I was having two normal bms daily until some kidney problems altered things but otherwise it was the best decision I ever made.
I will be more than happy to answer any questions you have.
I wish you the very best,
